Nope, you don't know the answer for SM at all. And they were never universally hated just because of the XY saltiness, that faded away by S1 itself. After ep20 SM had its sizable fanbase forming, that's because by then people had accepted what happened in XY and the changes SM brought. People didn't hate SM for itself back then mostly but for being after XY, XY not breaking the status quo again so there being saltiness and the new artstyle and direction. Once people got over their petiness they enjoyed the series for what it was since it always had a consistent theme going on with it. The people who liked that ended up loving it. If not by ep21 definitely by the misty/Brock two parter and before the nebby arc SM was no longer universally hated and had a very sizable fanbase that supported and defended it for a long time, yes EVEN before the league was confirmed to happen. The league was just a cherry on the top, ending the saga on an extremely high note and satisfying manner! It isn't the reason SM is beloved and saying it is just invalidating the earlier fanbase and forming a false narrative
Yea..... probably shouldn't have taken the bait but I'll bite. It never was 'bad' just because you don't like it. Unlike BW it didn't have production issues and writing issues that led to no proper arc resolution or story. SM had its own direction themes and arcs going which they concluded perfectly. It's fine to not be a fan of that direction and so not to like but to those for which that style fits, it's a great series to watch
Thank you! Someone who was actually there and know the fanbase state lol. Heck it was ep20 (the Pikachu and Ash alone in an island) which got very great feedback and just being followed up by the litten episode made lots of people put aside their negative bias and enjoy the series for what it is, surprising them. Even before there were lots of people adjusting to and liking what SM was doing but the ep20-21 boost was very significant! It's when SM's fans particularly started to form, not just anipoke fans liking SM coz it was the next series. And by the misty/Brock two parter and just before the nebby arc (the hype for it was fun lol), it's fanbase was pretty significant. The league was just a cherry on top, not the reason.
